My 1999 honda civic with 175,000 miles won't start. Pprior to this problem I started to experience a jerking movement upon accelaration while driving. Also when the clutch was disengage or in neutral I still had that jerking movement. I changed the timing belt at 90,000 miles. Now when I crank up the ignition it won't turn all the way. What might be the precise problem. Thank u
